TRANSCEIVER FSK Version: 434 MHz Band / 868 MHZ Band / Code: 3-2000519 / 3-2000519A DESCRIPTION: The 3-2000519 and 3-2000519A modules are fully programmable multichannel PLL based FSK transceivers, with dual IF conversion and software channel selection in the 868 Mhz (p.n. 3-2000519A) and the 433 Mhz (p.n. 3-2000519) ISM bands. The typical transmission output power is 10 mW ( +10 dBm ) and the sensitivity in receive mode is 108 dBm. The dual IF conversion, together with the SAW front end lfi ter, allows for a highly selective module, with outstanding side channel noise immunity, ideal for industrial applications and wireless RS232 and RS485 replacement.

In all versions using a front end SAW filter, the bandwidth is limited to about 2 Mhz within the ETSI ISM 433 435 Mhz and 868 870 Mhz bands. The transceiver can still move within the above bands, with a 200 Hz resolution. This allows for a very precise tuning of the carrier frequency and the ability to implement 25 Khz channels if required. Switching from one frequency to another takes about 50 us for a 100 Khz variation, so that frequency hopping algorithms can be implemented, if required. The transmitter output frequency can be set digitally by software, and is stabilised by a closed loop control. The RSSI signal can be read by the software with great accuracy, so that the output power can be matched to the strength of the received RF signal, optimising power as a function of the required range. The dual conversion architecture, with SAW front end filter and dual IF ceramic filter guarantees a very high noise immunity and perfect compliance with I-ETS-300-220 e I-ETS-300-683.
